I’ve had this for a very long time. It belonged to a family member who passed away years ago. She was vey well off. Not thinking about selling just curious. The only thing I know about this is that in the early 90s we stopped at a jewelry store to have the value assessed. The guy said 10k and offered to buy it. He was told no and we left. He followed us down the street raising the offer. I was there but do not remember that day. Another family member was there and told me the story. I have another picture that appears to be an 8 or two circles one above the other. Again not for sale. I’m just looking for any possible info about its origens. Any ideas?

Edit to add: It weighs 4.57 grams.
